How To MIG Weld: The Best MIG Welding Tips for Beginners

What is MIG Welding?

Welding permanently bonds two pieces of metal, and MIG welding is one of the most popular techniques for doing so. MIG is an abbreviation for “metal inert gas.” This term refers to the gas used to protect the weld as it’s being made.

While many people think of MIG welding as the easiest type of welding, it’s still incredibly useful and common in various industries, especially in construction and numerous factory settings.

What Can You Weld with a MIG Welder?

A MIG welder can be used to weld aluminum, stainless steel, carbon steel, cast iron, alloy, sheet metal, copper, square tubing stock and other metals. MIG welding is popularly used for repairing damaged metals, too. It tends to work best with somewhat thin materials.

What Supplies Do You Need to MIG Weld?

To begin using a MIG welder, you obviously need the welder itself and the torch that goes with it. Additionally, there are several MIG welding accessories you must have, including a power supply, wire feed, ground clamp and gas regulator. You’ll need canisters for carbon dioxide and argon, as well.

Beyond these tools, learning how to weld with a MIG welder requires several pieces of personal protective equipment to keep you safe while you work, including a welding mask or helmet, gloves, boots and welding sleeves or a jacket. If there are concerns with ventilation, you may also choose to use a respirator or equipment to extract fumes.
